Thirdlove

At ThirdLove, we believe great underwear starts with people who care deeply about fit, comfort, and inclusivity. Our product teams partner with real customers to design bras that feel like a natural extension of the body, not a constraint. We pioneered half-cup sizing and a precise sizing approach that helps every person discover a bra that truly fits. Based in San Francisco, our HQ draws on a collaborative, experiment-driven culture where feedback from Fit Experts and customers shapes every collection. We ship products with a focus on wear-testing and durability, and we obsess over details that improve day-to-day comfort - from fabrics to straps to back smoothing. We hire for curiosity, empathy, and the willingness to challenge norms in an industry long defined by one-size-fits-most conventions.

Beyond products, ThirdLove is committed to empowering women. Co-founders Heidi Zak and Ra’el Cohen built a company that values body positivity, inclusion, and giving back. Since inception, we’ve donated tens of millions in products to women in need, and we celebrate milestones like the introduction of 24/7 Classic bras and the Take Back Bag program. Our culture emphasizes collaboration, transparency, and a customer-first mindset - from how we answer support requests to how we evolve our loyalty program and Fit Finder experience. We take pride in a workforce that reflects the diverse body shapes we serve, and in a mission that extends beyond commerce to real-world impact.

We design with intention, test with real bodies, and communicate with honesty. ThirdLove is more than a brand; it's a community of people who care about helping others feel confident and comfortable every day. Our work environment supports growth, continuous learning, and shared accountability as we pursue better fits and better outcomes for millions of women around the world.
